I have purchased a android phone and I can see the Bluetooth devise and I can connect to it
The bT device has a micro push button however it has a EN connection not a KEY connection. The BT device (HC-05) is connected to the RX2 TX2 pins on the mega through a bi directional voltage logic circuit so not to blow the device. I can get the BT device to blink slowly ie on for 2 seconds and off for 2 seconds (ie in AT programming mode) or I can get it to blink fast say 2 flashes per second (looking for connection mode)
The problem is I can not get it connected when I run the communication option 3 the 2. It always fails.
I have undertaken some limited at programming using an ftdi adaptor so I know most things are working however I still can not get the device to connect to the mega.
I have followed the new instructions as closely as I can.
Any suggestions
